Optimization of the 7970 and 570 (and 460)

Go to the collatz message boards and go to number crunching. Look at the first post something like optimization for solo collatz 4.07. Use it! It cut 1400 seconds off my 7970 times and a couple of hundred off of my 570 and 460 times.

Actually, that's a good thing. It means Jon is back and is working on the validator issue. When it's back up, do check out the optimation sticky. It's pretty easy and either works well or doesn't do anything at all...like for my 430s.

So I had my 2nd 7970 on the bench putting on a new cooler. Just installed it and the optimizations had no positive effect. With or without the optimization it was only showing about 50% usage. I took out all the optimzation and just installed an app_config.xml using 0.5 cpu and 0.5 gpu (2 wus at a time.) I'm back up to 98 - 99% usage and it completes 2 in 30 minutes or 15 minutes/wu. A figure I can live with.

Edit:
I can't really give you good times on the 460 because of a heat issue (fubar cooler) I have to decrease volts to 900 and clock to 600 to keep it below 90c, but here goes:
460 @ 600 clock speed, memory 1800 ---> 4622 seconds (way to long)
460@ 625 clock speed, memory @ 1800 and optimized ----> 2818 seconds
Nothing else changed besides the clock speed and even being downclocked it decreased times by 1800 seconds, give it 1500 for the slightly higher clock and it's still worth doing.
